"Alex responded quickly to help me get six very old third story dilapidated attic windows replaced. He and his coworker came, measured and special ordered new windows at a fair price. They did excellent and efficient work in a difficult to work area. If you need windows replaced or repaired Wet Seal is who I would recommend. I appreciate all he did and the windows look great. Thank you Alex"

"I had a few things that I wanted done it all started with one bedroom window, five new window shutters and a front door shutter. The house being 41 years old needed a face lift. I also had them repair the front doorstep / sill. Family company that has a great crew and was able to complete everything in one day, I couldn't have been happier with the results and my wife is very happy to have all these repairs done. I highly recommend them and will use them in the future for other repairs"

"3 month wait for window installation during pandemic. Ordered windows on October 2020 and not scheduled to be installed until late January 2021. I guess anything of good quality is worth waiting for."

"The whole process went well, starting with the quote process all of my questions got answered quickly and through several discussions with Rich I ended up deciding on the combo of which windows I was replacing with which brand of replacements. I took a while to decide and asked a lot of questions and never was made to feel any pressure. The actual price was far better than the other quotes I got and I got no follow up from anyone else. The windows came in quickly and the installation crew was pleasant and professional and had the windows installed faster than I could have imagined, There was no evidence that they had been there except for the new windows. I am extremely pleased with the windows and am happy I went with Hunterdon. I can't wait until I can save up and get even more of my windows replaced!"

"I selected Marsha’s Cleaning Service, LLC from a group of possibles sent by the vetting service Angi’s. Marsha’s Cleaning Service had a long history with high ratings and great reviews. I was still blown away with the exceptional cleaning of my 44 windows and doors on 4 levels. The window screens were removed and scrubbed, window wells sanitized and windows cleaned like new. Her crew of three worked tirelessly over two days, inside and out of my home with covered shoes and care when removing and replacing barriers to the windows. Exceptional, skilled and efficient workers. I recommend them without reservation!"

"We had three older windows replaced because they were drafty and starting to show their age. The whole process was smooth, and the crew did a great job. The new windows look great, and we’re very happy with the results. I would definitely recommend them."

Windows FAQs, answered by experts

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.
